To all whom it may concern:

Be it known that I, WILLIAM C. POOLE, a citizen of the United States,residing at Marysville, in the county of Yuba and State of California,have invented certain new and useful Improvements in Cutting-Tools; andI do declare the following to be a full, clear, and exact description ofthe invention, such 16 to receive the adjusting screw 17, which is ithreaded into the extension 11 and provided with a lock nut 18.

'The shoulders 4 and- 6 are so formed with relation to the pivot bolt 3that when the jaws are closed in the act of cutting they are I stoppedtemporarily with their cutting edges out of engagement with each other.This temporary stopping of the cutting jaws is caused by the friction ofthe jaw 4 engaging the lower edge of the jaw 6, which is slightlybeveled and over which the jaw 4 is ada ted to wipe. It Will be seenthat if the shou ders 4 and 6 of the jaws were formed on a radial linefrom the ivot bolt that the abutting of the two wouid be solid, andfurther movement would be prevented, but as the shoulder 4 issubstantially parallel with the longitudinal plane of the tool, and theshoulder 6 is diagonal to said plane the shoulder 4 only engages itslower edge at iirst. Upon suflicient pressure being exerted upon theoperating handles, however, the friction is In the drawings, Figure 1 isa side eleva Overcome and the shoulders 4 and 6 will slide tion, Fig. 2is a longitudinal section, and Fig. over each other to a slight extentand allow 3 is a detail perspective view of the left jaw. the cuttingedges to come together. As soon Fig. 4 is a section on the line 4--4 ofFig. 1. as the handles are released the jaws slide eferring moreespecially to the drawings, back and separate the cutting edges. This 1and 2 represent the handles of the device, action is possibly due to thefact that the Which are pivoted together adjacent their pivot bolt hassome inherent resiliency by upper ends by a bolt 3.

The angle to the longitudinal plane of thelevers, latter jaw 8 has an extension 11 substantially and a shoulder oneach jaw formed parallel parallel with its handle, which extension iswith the longitudinal lane of said levers and as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to cutting particularly to that type of tootrimming horses hoofs.

The object of the invention is to provide a device of this characterwhich Will be chea to manufacture, rapid in operation and whicli pliers,and used for the cut. t A further object of the invention is to providemeans for limiting the stroke of the jaws so that the cutting edges ofthe tool will not come together and be fractured. l
